Tailings Mineral Industry Solution For example, a tailings stream in an iron ore application could be thickened to 4550 solids Newtonian slurry in conventional or high rate thickeners.
Dec 21, 2016· Its long been known that placer miners are losing almost half of their gold in the traditional recovery process, which relies on mills to separate the gold from the ore and then traps the liberated gold by means of gravity as it is washed down a sluice. But as much as half of the gold ends up in the tailings. These are the tiny particles
